Two countries, Belarus and China, have dominated the men's aerials at the last three Winter Olympics and look to do the same this time around in Pyeongchang.
While traditions, resources and basic geography often sustain the same rivalries in Olympic events, the long-standing duel in the acrobatic skiing event of aerials pits two countries with very different backgrounds against one another.
The unlikely pairing of Belarus and China have won six of the last nine medals in the men's aerials, including all three golds.
Belarus, through Anton Kushnir in Sochi and Alexi Grishin at Vancouver, have claimed gold at the past two games, twice relegating the Chinese competitor to third place.
China's Xiaopeng Han was the victor in Turin in 2006, edging out Belarusian Dmitri Dashinski into second.
The two nations are also strong in the women's event, with five medals between them since 2006. However, Australian Lydia Lassila, gold medalist in Vancouver and bronze winner in Sochi, can never be ruled out as she hopes to appear at a record fifth winter games.
Following the latest round of the World Cup in Moscow on Saturday — won by American Kiley McKinnon — Belarus' Hanna Huskova leads the overall standings, followed by China's Mengtao Xu, who won the World Cup last year in the women's aerials.
Last season, every single World Cup men's aerials event was won by either Belarus' Kushnir — who went on to claim the title — or one of three Chinese athletes.
This year is no different, with China's Zongyang Jia leading the standings. Kushnir is second, his compatriot Maxim Gustik is third and Qi Guangpu of China is in fourth.
The depth of quality among the two teams is staggering, with each possessing four athletes in the top 14 in the World Cup rankings, making it difficult for other nations to even dream about reaching the final in Pyeongchang, let alone claiming a podium place.
Speaking to Reuters shortly before the World Cup event in Russia, the head coach of the Belarusian freestyle skiing team, Nikolai Kozeko, said his nation's aerial prowess stems from the country's rich traditions in acrobatics and gymnastics.
"We are not strong in all disciplines of freestyle," admitted Kozeko.
"Our strength is aerial skiing. Belarus has strong acrobatics, diving and gymnastics traditions from the Soviet era and that has helped the creation of training centers for aerial skiing. These training centers were founded on the traditions of these sports."
China also has a history of success in gymnastics, and Kozeko believes these skills are perfectly suited for assimilation into aerial skiing, where athletes perform similar twists, turns and somersaults to achieve scores.
Maintaining dominant success is a challenge for any national sports program, yet China and Belarus seem to have the traditions, talent and structure in place to continue their hotly-contested battle for aerial supremacy into Pyeongchang and beyond.
